EXECUTIVE SUMMARY

This wiki documents Group 7\'s reverse engineering of the GM 2.2 Liter 4-Cylinder Inline Engine throughout the Fall 2011 semester. The purpose of this course project was to investigate the product design, functions and correlations of subsystems, and relate specific design aspects to the global, economical, environmental, and societal factors that were considered with respect to their function, and decisions made related to their functionality.
The primary function of the GM 2.2 Liter 4-Cylinder Inline engine is for use in commercial vehicles to allow for user transportation. Our group\'s dis-assembly of the engine allowed us to analyze the engine piece by piece. This not only allowed us a look at the function of each individual component, but through reassembly and direct analysis we were able to relate each component\'s function to one another, and correlate them into their respective subsystems within the engine.

Gate 2: Product Dissection

This gate is a documentation of our group\'s disassembly of the engine. It provides our step-by-step process of physically deconstructing the engine, along with an assessment of our work and management plans.

Gate 3: Product Analysis

This gate provides our group\'s in-depth analysis of the engine. It summarizes the components basic features and manufacturing processes, offers a product analysis with respect to the four factors, a CAD drawing of some of the parts, and design revisions at the component and subsystem levels.

Gate 4: Product Reassembly

This gate documents our group\'s reassembly of the engine. It provides a step-by-step process of reassembling the engine and compares it to the original assembly. It also provides a final assessment of our group\'s work, and some design revisions for the engine at the system level.
